the "perfect" max load should be the number of cpus you have,
so a quad-core server can sustain a load of 4 without a
It's an awfully good question, but there probably isn't a single right
answer. My server is a quad-cpu beast on a gigabit network, but I settled
on two backups at a time after measuring degradation (first back up one at
a time, then two, then three...) Then again, neither my file system nor
